LOAD-RETAINING APPARATUS FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 686,587, dated November 12, 1901.

Application filed April 8, I

To all whom it may concern:

Be it known that I, WILLIAM MARTIN CAIN, a citizen of the United States, residing at Carlton, in the county of Carlton and State of Minnesota, have invented certain new and useful Improvements in Load-Retaining Apparatus for Vehicles; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain improvements in load-retainin g apparatus for loggingcars or other vehicles, and particularly to that class of such devices adaptable for use as skids.

The object of this invention is to provide a simple, economical, and improved means whereby logs and other heavy articles may be loaded or partly loaded on the car, retained in position thereon, and unloaded therefrom,

- as desired.

With this object in View the invention consists in certain novel constructions, combinations, and arrangements of parts, as will be hereinafter described and claimed.

The accompanying drawing represents a portion of a logging-car with my improvements applied thereto.

Referring to the drawing, A designates one end of a portion of a car-body of common and well-known form, to the upper surface of which and extending to opposite ends thereof is fastened, by any desired securing means B, the irregularly-shaped metallic strap 0. At each end of this strap 0 and formed inte gral therewith is the bifurcated head D, provided withan aperture, as at d, for the reception of a pintle (Z E is a metallic socket of any suitable metal, preferably of cast-steel, cut away at its lower end, so as to form a strap or tongue, said tongue being adapted to be turned about the pintle d thereby forming a hinged connection between the strap C and the socket E. A standard F, preferably of wood, is inserted into the socket E, thus forming means for retaining the logs securely inplace on the car when in its approximately vertical position and adapted when in an approximately horizontal position to provide means for load ing or unloading the logs or other articles.

901. Serial No. 54,874. (No model.)

In order to retain the standard E in its approximately vertical position, I provide a chain G, which is fastened at one end to the socket in any desired manner. This chain passes along the side of the car or, if desired, along the side of the bunk in an approximately parallel position thereto and after passing through the ring H, secured by the staple I to the car, is fastened or held in position by means of a hook or pin preferably'attached to an auxiliary chain K, secured to the edge of the car-body by means of the staple L. Ahook M at the end of chain K is passed over or through the chain G, thereby securely looking it, thus holding the standard E in an approximately upright position. If desired, the ring I-I may be omitted and the chain passed through any modified form of the staple I. The loose end of the chain G may be allowed to hang free or may be wound on any suitable form of windlass attached in any desired manner to the car, or it may be coiled in a box or other suitable receptacle on the car. Said straps (3 may extend in a general longitudinal direction with respect to the body of the car, in which case two straps might be arranged to cross each other at about the center of the car, and the stakes would, when released, fall outwardly from the ends of the car 5 but preferably said straps are arranged transversely of the car, one of said straps near each end of the car, so that when released the stakes will fall outwardly from the side of the car. In either case the stakes in lowered position are adapted to be used as skids. If desired, a portion of said strap 0 may be cut out or omitted, so that each stake will be supported by an independent strap or bracket.

It will be observed that all parts of said device are exceedingly simple of construction and for the most part easily capable of being made or repaired by the camp blacksmiths or in shops of small capacity, that the stakes may be released without danger to the operator from the falling load ,that each stake is substantially independent of the other, and that the construction is simple, cheap, durable, and effective and easily applicable to average cars. In operation the stakes under loadpressure are released by striking upward the pin or hook M to disengage it from the chain G, whereupon the pressure of the load forces the stakes outward and downward.

I am aware thatit has heretofore been proposed to employ logging-cars with pivoted stakes or skids at their ends; but these devices have been of such a nature as to unfit them for the purposes for which my structure is particularly adapted.

Having thus described my invention, what I claim is- 1. The combination with a vehicle, of a strap extending across the upper surface thereof, and sockets pivoted at its free ends and carrying removable car loading, retaining and unloading apparatus,substantially as described.

2. The combination with a vehicle ofa strap extending across the upper surface thereof, and a socket pivoted to said strap.

3. The combination with a vehicle of a strap extending across the upper surface thereof, a socket pivoted thereto at each of its free ends, and standards adapted to be carried by said sockets.

4:. The combination with a vehicle, of a strap extending across the upper surface thereof, a socket pivotally connected thereto and carried thereby at each of its free ends, standards adapted to be carried by said sockets and means for locking the sockets in an adjusted position.

5. The combination with a vehicle of straps or brackets secured thereto and extending outwardly from the sides or ends of the vehicle, a vertical swinging socket pivotally connected or hinged to each projecting end of said straps or brackets and adapted to re ceive a standard or stake, and means extending from each of said sockets to the relatively opposite end or side of the vehicle for locking said sockets and standards in loadretaining position substantially as described.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

WILLIAM MARTIN CAIN.
